Application December a, 1941, Serial No. 422,148 2 Claims. (01.146-28) The present invention relates to new and useful improvements in peach stoners and has for one of its important objects to provide, in a manner as hereinafter set forth, a machine of this character comprising unique means for receiving and holding the fruit while the stone is cut or severed from the meat of said fruit.

Another very important object of the invention is to provide a machine of the aforementioned character which is adapted to halve the fruit in addition to removing the stone therefrom.

- Other objects of the invention are to provide a peach stoner of the character described which will be comparatively simple in construction, strong, durable, highly eflicient and reliable in use, compact, sanitary, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanyingdrawcharacters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan view of a peach stoner constructed in accordance with the present invention.

Figure 2 is a view in vertical longitudinal section through the machine, taken substantially on the line 2-2 of Figure 1.

Figure 3 is a vertical longitudinal sectional view, showing the carriage in forward or projected position. 1

Figures 4 and 5 are cross-sectional views, taken substantially on the line 4-4 and 55 of Figure 2, looking in opposite directions, as indicated by the arrows.

Figure 6 is a detail view in perspective of the stationary front blade.

Figure '7 is a detail stoning knife. Figure 8 is a detail view in perspective of one of the movable rear blades.

Figure 9 is a top plan view of the carriage.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a horizontal cylindrical housing housing I is provided with legs 2 which rest on a bench'or other suitable support 3. The legs 2 may be secured to the support 3 in any desired manner.

The lower portion of the housing I is formed to provide a depending hopper 4 for the reception of the stones as hey are view in perspective of the I of suitable metal. The

said hopper being provided with a discharge opening 5. The upper portion-of the housing I is formed to provide an opening 6 for the insertion of the fruit, as at I, Fig. 2. The forward end of the housing I is open and projecting therefrom knife 9 in the recess I0 is a pin II, the purpose of which will be presently set' forth.

An internally flanged ring I2 is threaded on the other end portion of the housing I and secures thereon a plate I3. A carriage, designated generally by reference numeral I4, is operable longitudinally in the cylindrical housing I.

The carriage I4 includes a substantially U- shaped handle I5 the legs of which extend slidably into the housing I through the plate I3. Mounted on the handle I5 and operable in the housing I is a piston I6. The piston I6 comprises a pair of spaced, opposed, segmental sections I1 which are fixed on the free end portions of the legs of the handle I5. The opposed faces of the piston sections I! have formed therein complemental recesses I8. Projecting forwardly from the sections ll of the piston I6 are resilient fingers IQ for receiving and gripping the fruit I.

Also extending slidably through the plate I3 into the rear end portion of the cylindrical housing l is a comparatively short, substantially U- shaped handle 20. Blades 2I are fixed on the end portions of the handle 20 for cutting the rear end portion of the fruit I. Coil springs 22 retract the blades 2!. Tubular casings 23 on the plate I3 enclose the coil springs 22. The legs of the substantially U-shaped handle 20 pass longitudinally through the casings 23. The blades 2I, when in retracted position, are located between the spaced piston sections ll.

Projecting rearwardly from'the plate I3 and communicating with the housing I is a centrally located cylindrical chamber 24. Rotatably and slidably mounted in the closed rear end of the chamber 24 is a shaft 25. An arcuate stoning v knife 26 is provided on the forward end of the shaft 25, both edges of said knife being sharp. An operating crank 21' is provided on the rear end of the shaft 25. The cylindrical chamber 24' and the piston recesses l8 receive the knife 26 when removed from the fruit. said knife is in retracted or inoperative position.

drawings. 1 It is thought that the operation of the ma-' chine will be readihr apparent from a consideration of the foregoing. Briefly, the fruit to be stoned and halved is placed in the cylindrical housing I through the opening 6 and engaged in the resilient fingers I! which hold said fruit in position in longitudinal alignment with the knife 26. The shaft 25 is then moved forwardly for inserting the knife 28 in the fruit from one end thereof, said knife being forced into position relative to the stone of the fruit, as at 28, to the curvature of which said knife substantially conforms. The crank handle 21 is now turned for revolving the knife 28 around the stone 28, thus cutting saidstone from the meat of the fruit. The handle 20 is moved forwardly against the tension of the coil springs 22 for causing the blades 2| to cut the rear end portion of the fruit longitudinally. The blades II and 9 are in alignment. The carriage I with the fruit I thereon is then moved forwardly in the housing I, as seen in Figure 3 of the drawings. In this manner the fruit is forced past the knife 9 which completes the halving of said fruit and the pin ll engages and ejects the stone 28. The stone drops into the hopper 4 and the halves of the fruit are directed into a suitable receptacle (not shown) by the chute 8. The carriage I 4 is then retracted and the machine is ready for the next operation. The stone is ejected from the fruit through the complemental recesses l8 in the piston sections ll.

It is believed that the many advantages of a peach stoning machine constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details mounted in the open end portion of said housing, a piston in operative alignment with said blade operable in the housing, means for supporting a fruit on said piston, blades slidable in the housing for cutting one end portion of the fruit, the piston including spaced half-sections for the reception of the slidable blades therebetween, and means for actuating the piston in the housing for forcing the fruit past the stationary blade.

2. A machine of the character described comprising a horizontal, substantially cylindrical housing having an opening for the reception of fruit, said housing being open at one end, a stationary blade in the open end portion of the housing, a substantially U-shaped handle extending slidably into the hous 8 through the other end thereof, a piston in operative alignment with said blade operable in the housing and comprising opposed half-sections mounted on the end portions of the handle, resilient fingers projecting from the piston for supporting the fruit thereon, a second substantially U-shaped handle extending slidably into the housing through said other end thereof, slidable blades mounted on the ends of the second-named handle for cutting oneend portion of the fruit, the piston sections being spaced from each other for the reception of the slidable blades therebetween, means connected to the second-named handle for retracting the slidable blades, the first-named handle constituting means for forcing the fruit forwardly in the houslngpast the first-named blade.
